Criminals store physical cash, precious metals, or other illicitly acquired assets in safe-deposit facilities offered by financial institutions. By placing such assets beyond direct transaction records, they complicate detection efforts and can make phased withdrawals or staggered deposits without triggering typical AML thresholds. Some business express deposit boxes also provide higher depositor anonymity, further hindering compliance oversight. Criminals often pay rental fees fully in cash and avoid retaining lease documents at their residence to prevent any paper trail connecting them to the box. In some cases, they exploit lax identity checks by using third parties or signing under false identities, and store contraband (such as drugs or firearms) alongside illicit funds. In jurisdictions where national banking registries include safe deposit boxes, stronger oversight may drive criminals toward smaller or non-reporting banks to maintain secrecy.

Tactics
Criminals physically store illicit assets in safe deposit boxes, often under false or obscured identities, thereby keeping them off typical account records and avoiding direct AML oversight. This deliberate tactic complicates detection, facilitates anonymous deposits or withdrawals, and preserves secrecy around both the assets and their beneficial owners.
Risks
Safe deposit box services inherently enable criminals to store physical assets (cash, precious metals, valuables) outside standard transaction records. Minimal or lax identity verification for box rentals and the ability to pay fees in cash allow users to maintain anonymity, stagger deposits and withdrawals undetected, and circumvent typical AML thresholds. These product-specific features form the core vulnerability exploited by this technique, making it the primary risk.
Criminals deliberately choose or relocate to smaller or non-reporting banks in regions with weaker safe deposit oversight or no centralized registry requirements. By exploiting these jurisdictions' reduced regulatory scrutiny, they maintain asset secrecy and evade stricter AML controls in more regulated locales.
Indicators
Unusually large or frequent cash payments linked to deposit box rental fees.
A client accesses multiple deposit boxes across different bank branches without a clear legitimate explanation.
A deposit box is rented in a location significantly distant from the customer's listed address or primary business location without a plausible reason.
Frequent renewals or changes in deposit box rental arrangements without clear, legitimate business justification.
Utilization of deposit boxes in jurisdictions with weak AML controls or high secrecy standards, absent a legitimate business or personal rationale.
An individual rents a deposit box with no plausible personal or business need for secure physical storage, based on their known profile.
Reluctance or inconsistency in explanations during due diligence inquiries about the future contents or purpose of the deposit box.
Customers insisting on anonymity or providing incomplete addresses.
Low-income clients renting disproportionately large, expensive deposit boxes or multiple boxes.
A client with known criminal affiliations or under active investigation who maintains one or more deposit boxes.
Frequent deposit box visits soon before or after large or structured cash transactions in the customer's accounts, lacking a valid explanation.
Data Sources

- Aids in enhanced due diligence for customers who may be concealing illicit assets.
- Provides risk ratings and AML regulatory conditions across various locations.
- Highlights banks operating in high-secrecy jurisdictions where criminals may prefer renting deposit boxes.
- Assists in identifying elevated risk scenarios stemming from deposit box usage in weak AML environments.
- Consolidates information on all financial transactions, including the timing and amounts of safe deposit box rental fee payments.
- Allows correlation of cash deposits or withdrawals with safe deposit box usage intervals.
- Helps identify structured cash payments or other anomalies tied to the deposit box rental.
Authenticates and validates official identification documents, helping detect forged IDs or inconsistencies when criminals attempt to rent deposit boxes under false names or third-party identities.
- Records each access event, including the date, time, and identity of the authorized user.
- Enables the detection of unusual or frequent visits that may indicate illicit storage or transactions.

- Facilitates early detection of inconsistencies (e.g., no plausible reason for needing physical storage).
Mitigations
Require thorough, documented identity verification and background checks specifically for safe deposit box renters, with additional scrutiny for customers paying rental fees in large amounts of cash or requesting multiple boxes. Verify any authorized representatives and apply heightened ongoing monitoring to detect patterns indicating concealed ownership or third-party usage. This targets the vulnerability of criminals exploiting lax identity checks and concealing illicit assets in deposit boxes.
Establish strict internal protocols requiring staff to flag frequent deposit box visits, recurring large cash payments for box rental, and requests for multiple or unusually large boxes without plausible justification. Mandate senior management or compliance approval for high-risk deposit box rentals and ensure each box access is logged with a verified ID check. These procedures directly mitigate unchecked anonymity and repetitive suspicious usage of safe deposit boxes.
Maintain comprehensive, auditable records of all safe deposit box rentals, including each lessee’s verified identity, any authorized representatives, and detailed logs of every box access. Require a reliable ID check upon each access to prevent anonymous or unauthorized entry. These records specifically address the hidden asset storage vulnerability by creating an accessible audit trail should suspicious deposit box usage arise.
Establish or participate in secure information-sharing channels or national safe deposit box registries to identify customers renting multiple boxes across different institutions or jurisdictions. This collaboration specifically addresses the tendency of criminals to exploit uncoordinated deposit box oversight by dispersing illicit assets where local policies are weaker or less cooperative.
Instruments
- Criminals store valuable metals and gemstones (e.g., gold bars, diamonds) in safe deposit boxes to conceal them from traditional banking records.
- Because these assets are compact, high-value, and not easily traced, the deposit box environment helps obscure ownership and provenance.
- By paying box rental fees in cash and avoiding recordkeeping, criminals further reduce the likelihood of detection or asset tracing by authorities.
- Criminals hide portable, high-value artistic or historical items in safe deposit boxes to avoid creating transaction records.
- Storing these pieces off-site and paying rental fees in cash helps cloak beneficial ownership, preventing direct ties back to the illicit funds used to acquire them.
- The absence of formal documentation or appraisal reports in the deposit box environment further complicates due diligence by financial institutions and law enforcement.
- Criminals place large sums of illicit physical currency directly into safe deposit boxes, sidestepping traditional bank deposit channels.
- By paying the rental fees in cash and avoiding formal account deposits or withdrawals, they can bypass reporting thresholds and reduce transaction scrutiny.
- The anonymity of safe deposit boxes allows staggered or phased withdrawals of illicit cash without triggering AML alerts linked to structured cash deposits.

Actors
Illicit operators exploit safe deposit boxes by:
- Placing physical cash, precious metals, or other illicit assets into boxes to hide funds from transactional records.
- Paying rental fees solely in cash and avoiding documentation that could link them to the box.
- Relying on staggered deposit and withdrawal patterns to avoid triggering reporting thresholds.
These methods help criminals evade detection by limiting visibility into their assets, posing a significant challenge for financial institutions' efforts to trace illicit proceeds.
Nominees facilitate the concealment of ownership by:
- Renting safe deposit boxes on behalf of others, obscuring the true user.
- Allowing criminals to assume a false identity or exploit third-party details to bypass identity checks.
This arrangement further hinders financial institutions from identifying the actual party controlling or benefiting from stored assets, contributing to anonymity in illicit transactions.
